Different strokes

I did not find the article (Belle de Jour versus Julie Bindel, 1 May) to be very helpful at shedding light on the debate on the legalisation of prostitution. So Magnanti got some facts wrong, such as the number of researchers involved in some or other study – shock, horror. If academics had to resign every time they got a fact wrong, especially one so trivial, our universities would be empty. For what it is worth my view is that, if someone enters the sex industry entirely voluntarily, that is her choice, albeit one for which she should be pitied. However, I could very well be misguided, so it would have been nice to read a contrary argument.Professor Graham HallPenarth, South Glamorgan

• Sorry Mr Bevan, it has now happened, the first for-profit NHS hospital has been revealed (Road to recovery?, 4 May). I am sorry that I didn't protest harder. The spirit of your NHS has gone because everyone seemed to conveniently forget that NHS hospitals give care to patients, but private providers sell it to make a profit for shareholders. What a label for Hinchingbrooke hospital to carry.Jonathan HauxwellCrosshills, North Yorkshire

• An interesting article about Soweto Theatre (Report, 3 May) but, while the curving design is not particularly "reminiscent of Frank Gehry's architecture", there is no mention of the architects. This often happens with your coverage of new buildings – as if they were designed by committees. The architects for this project were Chibwe Afritects of South Africa. Now if Jonathan Glancey was still with you …Martin RyanBristol

• I thought Derry/Londonderry was called "Stroke City" (Letters, 2 May), not because its inhabitants are unhealthy, but because the "correct" way of writing it down was the use of the stroke punctuation mark (slash or virgule).Gwen MathewsBulwick, Northamptonshire
